How to mark skis for mounting

I just got a pair of 2011 161cm Ar7 skis. I want to mount them center but i'm going to put the "center" mark on because the ski only comes with -2.5 and -5.
However, when measuring the ski, instead of 161 cm long they are 160.5cm long.(Don't know why that is.) Do i put the center mark at 80.25cm(160.5%2) and have it be only 2 cm away from 2.5?
Or do i act like the ski is 161 and mark center at 80.5cm(161%2)
Or do i just measure 2.5cm up from -2.5 which would put it at 79.75cm?
I dont know why my center mark is only 2 cm away from -2.5. Shouldn't it be 2.5cm away?? -2.5 is marked at 82.25cm. Shouldn't it be at 82.75?
I know this is probably confusing, but please no stupid answers, need these mounted tomorrow! +k for good answers .Thanks!
 
It can be a great idea to make your own line instead of trusting the shop to do it. If you want it center, just follow the math. Make sure you are measuring right, and you can ignore the graphic. It is just a sticker on the ski. Trust your measuring tape.
 
^this, and you should look at how much distance 0.5cm is and think about how much it will effect your skiing.
 
put both skis together with tips both the same way then draw center mark on both skis. turn one ski round so they are tip and tail together, if the line matches up you have won
 
Find the centre of the running length, so you'll have equal length touching the snow in front and behind you. Most skis have lower tails than tips so if you mount at cord centre you end up with more tail than tip.
 
Given that the AR7 is not symmetrical in shape, sidecut, or flex, I would use this "version" of center.

When in doubt, measure chord center and mark it on the tape on your ski. Measure & mark the edge contact center (running length center). Measure & mark the step-down sidewall center. See where these measurements compare to the top sheet marks and what makes the most sense to you.
